How to Replicate RDS and EBS Backups Across Regions with AWS Backup

This SOA-C02 practice question tests your understanding of reliability and business continuity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: aWS Backup. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Regulatory requirements mandate that all RDS and EBS backups are replicated to a secondary AWS region within 24 hours of creation. The company has workloads in us-east-1 and must replicate backups to eu-west-1. Restoring from the secondary region must be possible without manual copying steps during a disaster. What service and configuration implements this requirement?

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Create an AWS Backup plan with a cross-Region copy rule that replicates recovery points to a backup vault in eu-west-1 within 24 hours

AWS Backup is the correct service because it natively supports cross-Region copy rules that automatically replicate recovery points (including RDS snapshots and EBS snapshots) to a backup vault in a secondary Region within a specified time window. This meets the 24-hour replication requirement and enables direct restores from the secondary Region without manual copying, as the backup vault in eu-west-1 contains the replicated recovery points ready for use.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Create an AWS Backup plan with a cross-Region copy rule that replicates recovery points to a backup vault in eu-west-1 within 24 hours

    Why this is correct

    AWS Backup's cross-Region copy rule runs automatically after each successful backup job. The copy is encrypted with the destination vault's KMS key. In a disaster, operators restore directly from the eu-west-1 vault — no manual cross-region data transfer is needed. A single backup plan can cover multiple resource types (RDS and EBS), satisfying the consolidated requirement.

    Related concept

    AWS Backup

  • Schedule a Lambda function that calls CreateDBSnapshot and CopyDBSnapshot to replicate RDS snapshots, and CreateSnapshot and CopySnapshot for EBS volumes to eu-west-1

    Why it's wrong here

    Custom Lambda scripts are a valid pre-AWS-Backup approach but require writing, testing, and maintaining custom code for each resource type, handling errors and retries, and ensuring the schedule reliably runs. AWS Backup provides the same capability as a managed service with no code required.

  • Enable RDS automated backups with cross-region replication and configure EBS snapshot copy separately using Data Lifecycle Manager

    Why it's wrong here

    RDS cross-region automated backup replication works for RDS only. EBS Data Lifecycle Manager (DLM) handles EBS snapshot replication. Managing two separate tools for two resource types duplicates the configuration and does not provide a unified view of backup compliance across both. AWS Backup unifies both.

  • Use S3 Cross-Region Replication to replicate the backup bucket containing RDS and EBS snapshots to eu-west-1

    Why it's wrong here

    RDS and EBS snapshots are not stored in customer-accessible S3 buckets. They are managed by the AWS service internally. S3 CRR applies to objects in customer-owned S3 buckets — it cannot replicate RDS or EBS recovery points.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume they need to use separate services (like Lambda or DLM) for each resource type, missing that AWS Backup provides a unified, managed solution that handles both RDS and EBS snapshots with cross-Region replication and direct restore capabilities.

Detailed technical explanation

How to think about this question

AWS Backup uses backup vaults as logical containers for recovery points, and cross-Region copy rules leverage the underlying snapshot copy API but add lifecycle management and compliance controls. The copy rule can be configured with a retention period and a time window (e.g., 24 hours) to ensure compliance, and the replicated recovery points are fully restorable in the target Region without needing to copy them back. Under the hood, AWS Backup uses the same snapshot infrastructure as native RDS and EBS, but automates the entire workflow, including encryption with KMS keys if needed.

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
